primary passage and establishing oirculation. v

To the attainment of the foregoing the in vention consists in the improvement as hereinafter described and definitely claimed In the accompanying drawings, hereby made a part hereof:--

Figure 1 is a vertical transvelse section of a radiator equipped with my improvement.

Figure 2 is a detail view showing the arrangement of the overflow relative to a por- 2 ti-on of a cellular radiator.

Figure 3 is a detail View showing the arrangement of the overflow relative to-a portionof a tubular radiator.

Similar numeraisof reference designate- 0 corresponding parts in all of the views of the drawings.

With the exception hereinafter set forth. the radiator may be and preferably is of the ordinary cellular or tubular type.

In the carrying out of my invention I provide an overflow conduit 1' which extends from the upper portion of the interior of the radiator to a point below the radiate where it is adapted to discharge.

Manifestly in the event of the water in the radiator freezing, steam or hot water will pass downwardly in the conduit 1 and by so doing will thaw the primary passage and re-establish circulation.

When the device is to be used in very cold climates I deem it expedient to provide the conduit 1 at a point below its upper end with a lateral intake arm 2 through which any appropriate fluid agent may in a heatedstate be conducted to the conduit 1 to keep the primary passage open and assure maintenance of circulation.

It will be apparent from the foregoing that notwithstanding its practical advantages as set forth, my novel radiator appurtenance is extremely simple and inex enslve and therefore will not materially'a to the cost of a radiator. It will also. be apparent that inasmuch as nothing except steam and hot water is carried throu h the conduit 1 there is vertically" no likeli 00d of the conduit 1 becoming clogged.

Having described my invention, what I claim and desire to secure by Letters Patent,

A. radiator characterized by a primary passage and by a conduit open at its upper end and having said end arran ed in the upper portion of the radiator an also having a discharge end located below the radiator, said conduit being relatively arranged to conduct steam or hot water downwardly through the primary passage, and being provided adjacent to its upper end with a lateral intake arm through which a fluid agent may in a heated state be supplied to the conduit.- In testimony whereof I aflix my signature.
